sPEcIFicA'rIoN forming pm of Letters Patent No. 626,834, dated 'June 1a, i899. Appnmnn mearbmry 28,1899. sean No. 707.155. m maar To all whom it 'mayconcern.- lle-it known that l, HENRY I. IIARRIMAN, a citizen of theUnited States, residingat New York, in the county of New York and State of. New York, have invented certain new and useful Improvements in Looms, of which the following is a specification, reference being had therein to the accompanying drawings. j vThe invention has relation to looms of that 1o class in which 'replenishment of the weft or filling that is being incorporated into the web or. fabric beingw'oy-'en is' effected automat.- icallytby the mechanism of the loom when necessity arises therefor-as, for example, on r 5 complete'or practically'complete exhaustion of'tho supply of weft or filling that is carried bythe working'shuttle or onloss of continuity ofsuch weft or filling-the action of the replenishing mechanism being brought about :o or instituted by suitable -orms of weft-indicator mechanism. fIns'ome forms of the said looms the replenishment is elected bymake inga change of shuttles,` the spent or failed working shuttle being retiredor dischargedz5 and a. fresh 01"reserve shuttle being introduced intoworking position in the loom, this latter shuttle havingits supply of weft -or filling i in proper conditionv to continue lthe weaving. I n n.ner cases-the working shuttle 3o has not been retired or discharged, but devices have been employed by means of which the filling-carrierin such shuttle, such fill-v ing-carrier having the form of a bobbin, a spindle, or a cop-case, has been ejected from the said shuttle and a fresher reserve fillingcarrier has been inserted into the shuttle, the latter being of a selfithrending character, so as to provide foran immediate resumption of the i'ntrodnctionof weft or filling into the 4o web or fabric beingwoven. In the'looms of.

the said class now generally known the replcnishing mechanism has been suddenly thrown intoactOn and the operations that aro incident to the replenishment have been '45 performcd"with the loom running at its usual full or regular-working speed. This mode of operation has the serious drawback that it occasions a col'isiderable shock to the loom and throws sudden and greatstraiu upon the 5o parts which are involved in effecting the de-b Y sired result. The necessityfor -be stated, for example,

. called into play eventing' the said shock and strain fromhei oming e.\'- cessive and causing injury, breakage, or derangement of the working parts compels the loom to be run 'at a regular working speed 55 'somewhat below what otherwise would be attainable,and `hence lessens the productiveness and value of the lo'on. ABy wayof making clearthereason for this necessity it may that in a l'oom` in which the automatic weft replenishment is effected' by making a change of shuttlequite complicated mechanismis required to be em-v ployed and quite a series Of mechanical ac-4 tions is required to occur-as, for-instance, Vthe releasing or opening of lthe shuttle-box swell or binder,the removal byliftingor oth'erA 'v wise of the front ofgthe sh u ttle-box, the ejecting of the exhausted or failed shuttle', the im serting of the n ewshuttle, die. These actions follow one another in quick succession. AThey must be timed properly. and very accurately with relation to one another and to the generalworking of the loom and must occurwith exact and u n'varyi'ng precision. I Ience when the shuttle -changing mechanism is vsuddenly and is required to perform its various functions at the full speedof the loom the stress exerted Orisuch mechanism and on -the loom is beth sudden and great and is ex# ceedingl y liable to occasion derangement and breakage or failure tooperate correctly. The same is essentially true also of looms in which a change of filling-carrier is caused to occur. Herein the number of actions that is required to be performed is somewhat less than when the shuttle itself is changed; buteveu greater delicacy and accuracy or precision in working are indispensable. An imperative requirement in connection with looms in which the flling-c'arrier'is changed fn'the shuttle is that the shuttle must be positioned with exactness in the sh uttle-box on the lay,'-olher\yise the filling-carrier cannot be changed. In addition va't'ter the change the filling must be threaded properly into the shuttle' while thelooni continues in operation. Delgacy bccomes the predominant feature of a loom in which the filling-earrier is changed. It is Very diicult to get the' shuttle to position roo itself exactly right in the shutticbox. Re hound thereof is `very likely te occur. A change of thesp'eed of a loom to thel extent of a few pickper minute, even such as might oe due to a defect in the engine or its running orto theslight increase in the speed ot" the engine which results from the throwing out .of operation of other machinery in the mill,

`will cause'the shuttle to rebund,although the parts of the loom previously were arranged ism is avery delicate mechanism both to buiid' and to keep in runnin" order, and the didicultios are very much increased by causing the same suddenlyto start into the perforim anceof its multiple functions, as well as con.- plete such performance, at. the full working speed 'of the loom to which it is applied.

Practical experience with looms constructedand equipped to effect automatically replenishmentof the weft or iiliing has demonstrated that Iin order to guard against failure in operation or derangement, accident, and breakage a slower rage of Aspeed than otherwise would be possible 'must be adopted for such looms'.

Certain main objects of the present invention are to provide fforlfacilitating in general the operations by which the replenishment of weft is cffectu-ted, whether that he by change of shuttle or by change of tilling-carrier, to eliminate all shock ahd strain i-ncident to bringing the replenishiug mechanism into action and during the performance of iis various,operatonsfto diminish or climi` nate the liability to derangement an'd to breakage resulting therefrom, and to enable the productiveness of. the loom to beincreased, if desired, by an increase in thespeed at which the loom normally is run. These objects in general are attained in accordance with the present invention by providing means under the control ofthe devices which institute the action of the'repleuishiug mech ansm, wherehywvlien the change of'wet't or- A filling is required to occur the driving of the loom rst is modified to occasion a dwell in 'the regular working of the loom, the devices hereinafter described operating to reduce the speed of the loom below that normally maintained during the regular working of the loom to a rate at which-the operation otthe replenishing mechanism' conveniently and safely may be caused totako piace, und whereby, further, the reduction of thev speed'of the loom maintained and the picking of the slinttie iserrested during several revolutions of t h so as to afford ample opreplenishment to be effect- By modifying the driving of the loom before the Weft-replenishing devices are brought into actionfreliev'e the shock that is incident to bringing the repleni-suing mechanism into action -while the ,loom is run-ning at full speed and also 4the. strain that is incident to the performance ofits functions, as well asthe tendency to accident-,derangement, and breakage. The reduction of the speed of the loom fon-several revolutions of the crank-shaft, with accompanying arrest of .the picking, and thegre'ater amount of time therebyallowed for the performance of such functions also tend tothe attainment of thse results.

My invention enables the loomto be'run at a rate of speed considerably higher between changes of weft. o'r iilling'than hasbeenfound practicable heretofore in the case of looms now generally known having weft-replenishing mechanism applied thereto, thereby adding considerably to ythe productiveness of the loom.y

Other objects oftheini'ention and various l additional improvements are disclosed in the course of the. following description.

IIl? is an injector or pusher for transferring' z5 at the proper timea shuttle from the said hopper over into the shuttle-bont on the corresponding end of the lay. vThe said injector is represented as having an 'arm 1S, by means of which it is supported from a pivot at 19 3o uponthe correspondingend frame of the loom. The transfer of a shuttle from 'the hopper to the said shuttle-box takes place when the lay ls in a forward position near the breibbeam. 2O 20 are bridging-pieces, which project from the bottom of the hopper 15, so as to facllitate the movement of the shuttle from the hopper to the shuttle-box. 22 designates the front wall of the shuttlebox at the supply end or change. end of the 4o loom. It. is made movable vertically, so as to permit it to be withdrawn from in front of 4the spent orfailed shuttle in the shuttle-box, whereby to permit of the escape or ejection of the said spent or failed shuttle from the 4 5 shuttle-box and also to permit a reserve shuttle to be'tansferred from the hopper 15 into' the empty or vacant shuttle-box by the acffionbf the injector 17. Herein the said front wall 22 is shown carried bythe forwardly-ex- 5o-tended arms 23 23 of a rocker 24, 'which is pivod at 25 to supports 2li, which extend rearwardly from the lay. A sprin g 27 acts to hold the rocker 24 and front wall 22 of the shuttle-box in their normal or working posi- ,28 2S, Figs. 1, 2, and 5, designate the usual swells or binders, which aro located at the rear of the shuttle-boxes.

lldesignalcs asmall rocker which is mounted upon the lay at the underside ol' the laybeam'and at the changecnd of the loom, it having an. amrl in engr-gement with the adjacent protector-finger, whereby when said rocker is moved as hereinafter described it acts to take the pressure of the protectorlingers off the swells or binders, and thereby facilitates the movement of the front 22 of the shutt1e-box at the change cud of the loom ad the entrance of the fresh shuttleinto the id shuttle-box under the action of the injector 17.

29 designates an ejector for pushing the spent or failed shuttle ont of the shuttle-box at the 'supply end or change end of the loom after the movable shuttle-box. front 22 has been moved out of the way, so as to permit. of the-escape of the said sh uttlc. This ejector 29 is in the form of a plate working beneath the lower edge of the swell or binder 28 at the 'change end of the -loom without interfering with the action of the latter. The ejector is held from rising out of proper position bythe said swell or binder above the same.

The hopper, injector, movable shuttle-box front, ejector, and rocker for relieving the pressure upon the swell or binder constitute the characteristic 'and essential parts, which are lnost immediately involved in the operations by which a change of shuttles is effected in the particular form of change or weft-replenishing mechanism which is presented in this case. They are combined` through inf strnmentalities which will presently be ex- `plained, with a shaft 33 or its eqnivalent,licre inafter known as the f change-shaft? and by means of which the working of such parts is occasioned or controlled. This change-shaft 33 is conveniently mounted in the loom. Herein it is shown carried by bearings at the rear of the loom. It normally stands stationary and inoperative, the various working parts of the change or weft-replenishing mechanism remaining .also in their normal inoperative positions. At the prcpertime, however, this change-shaft is caused to begin to rotate, and thereby ,brings into action the i aforesaid working parts of the change or weftreplenishing' mechanism'. The rotation of the change-shaft is initiated or begun unde the dictation of mechanism by which the condition of the weft or iillingbeing introduced into the web or fabric being woven is indicated. So far as this indicator mechanism is concerned it should be understood that while for convenience I have shown herein alsimple form of weft-fork mechanism acting on the breakage or failure of the weft or filling being woven in, yet in .practice any suitable adaptation of any of the other known forms or types of mechanism forindicating the condition of the weft or filling which is being introduced by the workin g shuttle may he employed without departure from thc spirit of the invention. This normallystaiibnarychange-shaft 33 has combined therewith a shipper orshifter mechanism-by means of whiclrtlievdriving of the loom is controlled.' Thus, having reference more particularly to Figs.2, 3, and 4 of the drawings, at the end of the loom which is opposite to that at which the change or replenishing mechanism is located the change-shaft 33 has fast thereon two cams 3l and 35. The cem 3i acts in connection with an sti-m36, which is fast on the rear end of a 'sleeve 37, the said sleeve beingl lied to turn frame, acts with a tendency to draw the beltshifter 39 into its position in Fig. 3, where it operates to hold the drivng-bend 4l upon the fast driving-band pulley 8. The driving-bend 41 serves to drive the loom during the regula'r working thereof. The cern 35 nets in con neotion'with en erm 42, whirl onncctcd with the hub 43, of a. second be hitter di. The said hub 43 is fitted or sleeved loosely upon the exterior of sleeve 37, and 'e spring 455, connected with the seid hula and also with some fixed point, nets with s idency to hold the belt-shifter i in the nnwvhich is shown in Fig. 1 it; tlvedriv ing-nano 45, wbr e throne/'ii the lfork llh of the said oeufon the il, pulley 46 on crimine-neit i. d' lose bend-pulley elli a bandqsnl fast on. the crankshaft 7, It is intended that drivingibnnds 4l and 4.5 shell both be driven from a suitable countsr'she't, ns ill, Figs. 2 and 3, but drivnfheni l5 rauch slower than driving-bend eil-ess for exemple, in conseqnence of applying the former to e pulley ll on said counter-shaft that is considerably less in diameter then the std oining pulley 452, to which drivingdmnd Lil is applied. During the regular running of the loom the drivint,t

' hund bend 4l. will be cansed to poss around fest band-pulley and drivingbsnd around loose band-pulley 46. Consequently the loom will be caused to work at the required high rate of speed.

It may here be explained tiret should it be desired to stop the loom at :my time dering the regular running or the loom this maybe effected by dislodging the shipper-handle 14 from the usual holdingnotch in the plate 141, whereupon the strong spring 491, which is connected with the shlpper-handle, will ron tate rock-shaft 38, the clutch-tooth 49 on the collar 50, fast on the said rock-shaft, engaging with a shoulder 5l on a collar 52, fast with sleeve 37, and turning the sleeve with its belt-shifter 39, so as to shift driving-band 41 onto the loose pulley 9, the resistance offered by spring;r 40 being overcome by the greater strength of spring 4S). During the regular running Y the loom the ends of arms 36 and 42 are c atusdi by the action of springs 40 and 455 to occupy positions in the lateral depressions 361 and 421, respectively, on th t sides of cams 34 and 35. When'shaftB is started to rotate at the dictation of the weft or filling detector or indicator mechanism, as referred to above, cem 34 acts then to move belt-shifter 89, so as to shift driving-band 4l from fast baud-pulley 8 onto loose pandpnlley 9, thereby taking olf the regular driving power. Cem 35 'also acts to move beltshifter 44, so es to shift the slowspeed driving-band 45 from loose band-pulley 4G onto fast band-pulley 47. As the said slow-speed driving-baud 445 passes onto fast band-pulley 47 itacts at first to retard the latter in its quickly to overcome the momentum of the loom and bring the speed thereof down to the desired low rete. While the loom is being driven :it e low rute of speed by menus of the driving-bond 45 passing around the fast bandpulley 47, the change or replenishment of weft or filling is cense'dto occur in consequence of the continued rotation of ohnnge-shnft 33.

)ne of the first actions occasioned by the rotation of the change-shaft is the arrest of the picking of the shuttle. This may be effooted in various ways. I have found the following means of accomplishing the saine efficacious, (see particularly Figs. 1v, 1, nnd fl of the drawingsc.) A cem 76 on the changeshaft 33 eels upon n. lever 77, the lutter having drenched thereto one end of o. connection '7i-i, which is made flexible in whole or in part,

/ehnnginf; pulley or sheave 79, from which lest the said connection extends downward and is attached to the lug-strep 8O at the change end or supply end of ,the loom. The inner end of the lug-strap is furnished with a hook, es 8l, which engages with a pin or cross-bar 82 on e block 83, which is attached to the nrm 84 of the picking rock-shaft 85. Vh-,n lever 77 is acted upon by cam 76, which occurs promptly after change-shaft 33 begins its rotation, the seid hook 8l is lifted off the pin or cross-bar 82, and thereafter the said picking rock-shaft movesv without transmitting motion to the 'picker-staff 5 on the change end or supply end of the loom until after the replenishment of weft or filling has been completed, whereupon the hook 8l is dropped into engagement with the pin or cross-bar S2 again. In order to prevent swinging movements of the lugstrap and flexible connection 78, which might interfere with the proper rengagement of hook 81 with the cross-bar S2, I provide a fixed guide 78 for the said flexible connection, the same being loc-ated between sheave'79 and lth'e lugstrap and being constituted by an armattached to the loom-frame and having a forked inwardly-extending lower end, between the branches of which the connection 78 extends.

In order to permit of the ejection of the spent or failed shuttle from the shuttle-box and the in ection of a fresh orreserveshuttle I raise the hutle-box front 22 out of the way. To effect this, the 'said change shaft has mounted thereon at the change end of the loom so as to enable it to pass around e directiony rotation and thereby to brake 'the loom, so'as IOO ` fected in various 5l) down into linewith .a

. depressing the rear arm a cani 53, (Shoud-separately in Fig. 6,) which acts upon one arm 'of theieellfcrank 54, the latter having connected withthe extremity of its other armone end .of afeomieetiony 55, which is made flexible in whole or in part to facilitate passing around adirection-changing pnlley or sheave 56which last is pivoted closely adjacent to the existan whichthe lay rocks. The otherend of .theconnecton 455 isattach'ed to the rearwardlye'extending arm 57 of the rocker 24, and when'the cam 53 begins to move the said bell-crank 54 the rocker 24 is`t'urned,

5.7 thereof and raising the front arms 23 23, together with the shuttiesbox front22.

The ejection of the spent'or failed shuttle from the shuttle-box on the lay may be ef- Ways. Herein a1 guide 58, with which arm 57 of the rocker is provided, receives. a'bolt'or front end 60 is loosely jointed to the rear end of the ejector 20, as by means of a slot-andpin' connection on` the order of that which is shown in Fig. l. By means of a spring or springs G1, connected-with bolt or slide 59 and with fixed portions charm-57 of therocker, the slide and ejectoraregheld normallyin their rearward position, the ejector being then withdrawn from the interionof the shuttle-box. The depression'of the rear arm-57 of` rocker 24 brings'the rear portion of the bolt or slide stop "62, that is appliedto a fixed bolt ,or slide encounters' the said stop, and thereby during the remaininglportion of the rearward .movcmenltnf or slide and the .'ejetor are held from fin-ther rea/retard movement, the result being that the spent orfailed shuttle is pushed out of the shuttle-box and falls forward oi the lay-bealn. As the lay advances toward the breast-beamagain the,ejector29-is drawn backwardly out of the spring or springs 61. breakage in in of the bolt orslide V6.9 should come down on top of the stop 62, the said stop is `made capable of yielding .to;downward pressureby being mounted on a pivot, as 63, it being weighted, as at 64, or otherwise acted upon with yielding forceto' hold `it in the normal working positioniereof.

It is'desirable that in order tofecilitate the operations which are incident to eiecting the discharge or retirem`ent ot' the spent or failed shuttlmbox by the shuttleand the injection o'f a fresh one the pressure of the weils or bindersshon-ld be reduced. Tothisendanothercam (designated and shownjsepamtely in Fig. 7) is mount ed uponfthe-'fchangeshaft 33.4 -t acts upon one arm of laboli-crank 66, to the upper arm ol which is connected one end of tion (57,.the latter being made flexible in whole or in part, to enable it to pass around a direction-changing sheave or pulley at 56 and havjti other end connected with the rocker slide 59which1latter at its portion of the loom-.frame 1V Consequently'as the'tlaygoes rearward .the-

Atheglay the-said boltl -In order toguard'against its descent the lrear end the said rocker is operated to relieve the pres- 7o sure on the swells or binders 2828, and this action is maintained unt-il after the shuttle- .box front has been dropped in order that no obstruction may be offered 'to the entrance of the fresh shuttle, which is to from the hopper 15. This operation of rocker 32 acts, moreover, to'hold the .dagger-125,01? the protector mechanism elevated during the advance of the lay which folJ the-knocking olf of the loom. l

For the purpose of operating the injector I employ herein mechanism las follows: A third cam (designated 68 'and shownseparat'ely in Fig. 8) is mounted on 33. It acts on one arm of a bell-crank 69, the other arm of the said bellfcrank beingunited by a connection 70 with the -arm 18 of theinjector 17; By this means the transfer of a lows the ejection l. of the spent or failed sliu tt1e so as toprevent 8o be transferred change-chat' t v8 5 reserve shuttle from hopper 15 to the empty 9o or vacant shuttle-box is. effected. The cam 68 has a concentric portion 71, extending around a considerable portion of the circumference thereof andv acting' to maintain the injector. normally in anintermediate position, (see Fig. 1,) with then-ear portion thereof within the hopper and 'extending beneath theo bottom shuttle of the stack of reserve shuttles in hopper 15, so 'as to support the `said bottom shuttle in an elevated position, whereby'it will be held above. the opening in the .rear side of the hopper st the lower end of the latter, and thereby will be, prevented from being caused by the jar of -the loom to pro ject or fall out through saidopening into the way of the lay. lThe said cam 68 has also a drop, as at 72, which permits the injector tobe` carried forward or toward'the right in Fig. 1, as by the action of a springf73, so as to withdraw the injector from beneath the shuttle or shuttles in the hopper and permit the bottom one thereof to fall `into position in line with the opening inthev` rear side of the hopper and with the injector. The projection or 'rise 74 onl the said cam 68 causes the advance of thefinjectorfo inject or push a reserve shuttle into the shuttle-box from the hopper. A spr'ng75 is interposed between bell-crank 69 and arm- 18, and the throw of the projetionor rise 74'01'l cam 6b is suiciently great to occasion an excess volf movement of the bell-crank, so that,'the injector having been 'moved to place a reserve shuttle in the shuttle-'box on the lay and b eing held pressedagainst the shuttle asit lies in lthe shuttle-box, the tension of the' spring 75 operates to cause the injector to follow the lay rearwardly a shortdistance, still pressing against the shuttle and holding it in place, untilv the shuttle-box fron-t 22 is lowered onto vthe upper surface of the injector, after' which the lay will separatefrom the injector and the shuttle-box front will drop on the latter and down intoits regular operative position.

said disk ha'ving in its periphery a no,tch,as

121, to receive a stud or pin 122, carried -by a locking arm o r lever 123, thesaid lever ing scteduponby a spring 124,which causes the stud orpin to be of the stop-disk and to enter the-saidnotch when the lat ter presen tsi tsel f,i n order thereby tovhold the change-shaftfrom further mta- In consequence of the fact that the weft-indicator mechanism kis actuated at a definite point in the revolution of the camshaft, while the change-shaft is stopped always in a -definite poslion,`therehy causing the loose sprocket-wheel@ and connected 'clutch m mber to stop also, with thetooth 00 in a give position, and of the further ,'fact that each clutch member is provided with butasingletootl1,it is evident that the changeshaft will always be'started when the lay is ata definite point in its movement. v

In order to afford ample opportunity for the performance of the various operations which are incidental to the replenishment of the working' weft-supply and secu re the desired ease and safety of action in etiecting replenishment, the actuating mechanism t' or the replcnishing instrumentalities'fis constructed and combined in the manner described elsewhere herein to extend the operations of the said replenishing instrumentalities throughout a -greater number of revolutions of the crank-shaft of the loom than two. It will be apparent from what has preceded herein that during this time certain of the usual worki n g members of the loom will continue in motion, among them being included the weft-indicating devices. inasmuch as the weft-i ndicating devices act at. every other revolution of the crank-'shaft lit will follow, from the. fact that noweft or filling is being introduced during the Working of the replenishing instrumentalities, that the said devices will rock the rock-shaft 104 several times before the normal working of the loom. is resumed, each -movemeut of the said rock-shaft serving-to advance the cam-disk 109 one step. The low spaces 112 112 between the cam projections 11.1 11i of the cam-disk 109 accordingly are respectively of an extent which is proportionate to the number of revolutions ofthe crankshaft before the chan ge-shaft has completed to provide for these id e actions of the weft-:indicator devices. So long as one'of the said low spaces 112 is presented to the arm 113 of the ch auge rock-shaft the tension of*Y nragainst-.the periphery 95 the spring 97 is free to act/to re turn the said rock-shaft to its normal position and open the change-clutch as soon as the catch 15 is disengaged from the arm 1li on the rock-shaft 95. I term the cam-disk 109 a device for intermittng the action oi' the weft-indicating devices npon the change rock-shaft. l

One aim of the present invention is to provide means for causing the ,first pekof weft after the replenishment of the working weft- `supply to be introduced into a predetermined shed in the warns in orderA .to obviate as far v as possible breaks in the weave of the fabric being produced. To this end the instrumentalities of my improved loom are contrived and combined tointroduce kthe first pick of fresh weft into a reopening of that shed in the round or cycle of shed formations which was deficient in its supply of weft or iilliug at the tir'neof the detecting action of the weft-indieating devices which broughtabout the weft replenishment. In the illustrated embodiment of theinvention the weft-indieatingdevices act to feel for the weft after each pick of the working shuttle vfrom the' change end of the loom to the driving end thereof, and shouldthe weft or filling be absent from ih frontof the weft-fork at such time the said devices bring about the change in the running of the loom, the arrest of the picking, and

the replenishment of the working wef'tsupply through the agency ofthe various instru,- mentalities which have been described.- The shed for which the weft-indicating devices act in order to occasion the working just dei scribed may be termed the first shed of s given cycle or round of shed formations. In accordance with theinvention the revolution of the change-shaft and the action of the instrumentalities connected therewith for controlling the driving, the picking-and the weft replenishi-ng arc-timed to keep the'loom running at slow speed with the picking arrested, the replenishment of the workingweft-supply being etected, meanwhile', for a plurality of shed formations, beginning the count `with 'thesaid ytirst or deficient shed and to restore the full speed of the loom and restart the pickingin season to cause the first pick of the fresh weft to be laid into a reopening of the said first shed. pended at time of replenishment for a plurality of rounds of picking (each round comprising a pick from change end of the loom to driving end thereof and a pick back to change end) and restarted at the end of a round or cycle of shed formations or`a multiple of such round or cycle greater than two shed formations, counting from a deficient shed, -to introduce the first pick of fresh weft into a reopening oi' the predetermined shed.

The embodiment of Vthe invention which is illustrated in the drawings has been designed with especial reference tothe employment of either two', three, or six harnesses, the parts being constructed and combined torestart the picking and the normal working of the Thereby the picking is suss ezeiesi loom after a. suspension of the picking. including the sixthvshed formation. As will be ob vio'us, when six harnesses. nre employed the operation of the described embodiment of the invention will'cnuse u suspension of the pick ing for just one round or cycle of shed formations. When either two or'three harnesses are employed incounection with the'said exnbodiment, it will be obvious that the resumption of weaving` will be effected after a nu1nber of shed formations corresponding with a multiple of the number of harnesses in use. The seventh shed is c repetition of the first., with which the count is begun, whether-tivo, three, or six harnesses be employed, and consequently in cases where the deficiency ci Weftoccurs in the said first shed the wea ring will be resumed by the pick through the seventh shed without any breek in the continuity oi the weave oi' the fabric being produced.

In the present case in order 1.o secure the resumption ofthe normal working of the loom in season for the seventh pick the change* shaft is driven from the camshaft at half the speed of the letter, thereby causing the change-shaft to mirko one revolution to four revolutions of the crankshaft. The gooseneclc engages with the we-foik and acts to move the weft-fork siide forward in the ioom at about the time ofthe second piek ci' the tailed shuttle. The next four picks lfire occupied by the working;` of the. replenishingr devices, the loom being changed to slow speed and the icking arrested, es above described, after which the normal ivm-king,l is instituted again in season for the seventh pick, ex plained.

The operation of recovering the deficient shed-i. e., the shed which is lacking in its supply of weft or filling-is known in the art as pick-finding." The devices ofthe prescnt case which cooperate in the recovery of the required shedwthat is, in providing `for the introduction of the first pick of fresh weft into the predetermined shed-may be termed forthe purposespof this case pick-finding instrumcntalities.

When using more than three harnesses, except where `six harnesses are employed, I contemplate sometimcs vuryingthe relative speed at which the change-shaft is driven through change in the driving connections in order to secure 'the desired results-that is to eey, in order to restart the picking et the end of a round -or cycle of shed fori-nations or n multple of such round or cyole. l prefer, howover, to retain in the loom the seme driving connections and continue tu drive the cha-ngesbaft at the same relative speed asin the prosent case and to secure the required number of shed formations prior tu the resumption of weaving, beginuingthe count with s. deficient shed, by permitting the weft-indicating devices to act idly one or more times before the change-dutch is closed. 'i his may be effected 4by simply increasing the extent of the spaces 112 112 between the'projeotions 111-111 on the in the present cese the weft-fork is located to,

'It is conceiv` the change end or supply'end.

eine that the seid shuttle may fail to complete such return and may be trapped in the shed. lf such is the ease, the trapping cf the shuttle wiil happen after the chunge-shnft has started to rotate. In order to provide egainstsuch a' contingency, the cams 34 and 35, which eiiect the transfer of the driving-hands, are set or timed so that the said bands shall not be shifted or transferred until after the loom has pussed the bottoni center succeeding the ne tiem-of the weifbforiz. In other words, the beitshifters 39 and 4i Wili not lie moved unii after the isy in its forward movement has carried the dagger beyond the engaging portion of the frol.,nr y126. Consequently should the shntrie have been trapped in the shed on its return to the 'change end or supply end the dagger w iii engage with the frog and knock 'placed in the hopper l5 at one time. `(See Fig. 1.) It is very difficult or practicallyim-v possible to get shuttles which eli size up exactly aiike, sind whiie in nse different shutties weer diorentiy, that their thickness is found to vary from time to time. Different sizes oi shuttles will fit ditierentiy in the shniilebos, sind .consequently will not enter or be reieined therein, exectiy the same.,

Coesequentiy in the course of the working of the loom the hitter is likely to siem off frequently owing te the rebounding of n. shuttle which not heid tightly euoughby the pressnreo" 'the swei". `or hinder. ifhrthermore,

when n reserve siuttle is introduced into the' shuttle-box at the change end or supply end of the loom it is ofneoessity pisa-ed somewhat in advance of the picker. remembered, inore'iver, that the picker commonly hes e'hcle o.e some depth worn in its striking-face by Contact with the tip of the shuttle. Thus in 'melting the first pick with the freshly-supplied shuttle the picker will travel an inch or 'so Jefore it encounters the shuttle, and 'this will result in giving a less effective driving blow than usual. To offset this loss in yelliciency`1 it is necessary toset the picking mechanism to vict with enough power lt will be` rio the shuttle; but this involves greater rack and strain on the loom in picking and a greater liability 'to break picker sticks and other parts.

In accordance with one part of my present invention I provide means for permitting the swells or binders to be set to act with sulicient force to counteract all variations in the sizes of the shuttles, whereby tendency of a small shuttle to rebound shall be overcome,

and also for permitting the shuttle to vbe picked with properforee to meet all requirements, while relieving the rack and strain incident to picking withinereased power. To these ends I combine with the protector devices a means of operating the same to permit the full pressure of the swells or binders to exert itself as the shuttle enters a box and to remove or relieve the greater portion of the pressure at the time when the pick takes place. Thus on one of the pitmen or connecting-rods 6 I pivot a lever 127, (see Fig. 2,) one arm of which engages with the adjacent protector-finger 30. The other arm of the said lever by the swing ofthe said conmeeting-rod in the rearward movement of the lay is caused to bear againsta cam, as 128, fixed 'upon the loom frame. Thereby the. said lever is turned upon its pivot 129 on the said connecting rod and caused to take the pressure of the protector-lingers off the swells or binders by rocking the protector-shaft just prir to the pick, after which the pressure is allowed to act again before the entrance of the shuttle into the opposite box. This enables me to exert an excess of pressure on the swells or binders and an excess of power on the picker-sticks without fear of racking the loom in the action of picking or causing breakage, and this is especially necessary in a loom having a hopper or magazine receiving` a plurality of shuttles which vary in size and weight. v

A modification of the speed-reducing devices is shown in Figs. 10 and 1l. In these figures I mount upon the crank-shaft 7, at opposite sides of vthe `usual fast band-pulley 8, two band-pulleys 130'and 131, respectively. 'lhe band-pulley 131 is an ordinary loose or idle pulley. The band-pulley 130 is also free to turn loos'ely on the. crank-shaft, it having fast therewith a sprocket-wheel133. Around the said sprocket-wheel 133 and also around a larger' sprocket-wheel 135, loose on calnshaft 12, a sprocket-chain 134 passes. Fast with sprocket-wheel 135 isa smaller sprocket,- wheel 136, around which and a large sprocketwheel 138, mounted looselyon the crank-shaft 7, a sprocket-chain 137 passes. 'lo the said loose sprocket-wheel 138 a series of gravitating dogs or pawls 139 139 is pivoted, the same being adapted for engagement with the teeth of a ratehetwheel140, which is fast upon the crank-shaft. 151 ,designates a single beltshifter which is affixed to a sleeve 142, mounted loosely'on the shaft 38 of the shipper-handle, the said sleeve having aiiixed thereto an arm, as 143, which is borne by a spring 144 toward a cam-disk 145, mounted upen changeshaft 33. While the change-shaft is at rest, during the normal .working ot 'the loom, the

action of spring 144 causes the end of the arm 145 to stand ina n'otch or depression 146 in the said cam-disk and the beltshifter 151 holds the driving-band on the fast band-pulley 8. During this time the loom is'beingV driven at its normal high-running speed, and ratchet-wheel v turns freelyl within the series of dogs or pawls 139 139, the sprscketwheel 138, by which such dogs or pawls are carried, remaining stationary meanwhile. When the change-shaft begins to rotate, the cam-disk operates to move the belt-shifter 151, so as to ltransfer the driving-band onto the band-pulley'130, whereupon the arrangement of sprocket-wheels and sprocket-chains willbe thrown into operation, the result of which will be that sprocket-wheel 138, with its series of dogs or pawls 139 139, will be set to turning slowly in the direction in which the crank-shaft is revolving. So long as the momentum of; the loom lcontinues to tiirril ratchet-wheel 140 at a higher rate of speed than the sprocket-wheel 13S the teeth of the ratehet-\vheel 140 will simply pass the said dogs or pawls; but as the speed of .the loom slackens, so that the crank-shaft tends to turn more slowly than the sprocket-wheel 138,

then the said dogs or pawls will take hold of the said teeth and act as dri-vers to continue the revolution of the crank shaft and the working of the loom, but at a predetermined low rate of speed. The collar 147, fast on shaft 38, is provided with projecting finger 148 to be engaged by the shoulder or projection 149 on the forward end of the sleeve. So long as the shipper-handle 14 remains seated in its holding-notch in plate 141 at 'the end of the breast-beam, the said notch being in this embodiment of the invention at the outer end of the slot in'said plate' instead of at the inner end of such slot, asin the case of the einbndif ment first described, the spring 1441 is prevented from carrying the belt-shifter 151 inward beyond the position thereof which places the driving-band on the fast-pulley 8. When, however, the shipper-handle is disengaged from its holding-'notch laforesaid, the said,

springr is permitted to turn bOth-the sleeve and the shaft 38 inwardly until belt-shifter 151 4places the driving-band upon the loose or idle band-pulley 131, and. thereby deprives the loom 'of its drivig-power, the end of arm 143 passing at this time farther through the notch or opening 146 of the cam-disk 145.
